LCN Processors

The K2LCN (68020 processors) is available in 2, 4, 6, and 8 Mw versions, and the K4LCN (68040 processors) is available in 4, 8, and 16 Mw sizes.
Larger memory sizes (such as 8 Mw) are available for the Universal Stations
to accommodate, for example, more memory resident schematics.

When determining the minimum memory requirements for each of
your nodes, be sure to consider any External Load Modules resident in
the node, and the possible increased memory requirements each of the
External Load Modules may have. Refer to the documentation for each
External Load Module to determine it's minimum memory
requirements.

Processor Compatibility:
The minimum memory capacity for the node processor is three megawords to support R500
software. A K4LCN (68040) node processor is highly recommended if your UCN is currently heavily loaded or if a High Performance Process Manager device is connected to your UCN. The K4LCN-4 node processor can be used in any node with one exception, a Universal Station running engineer personality requires 8M. Honeywell no longer sells K4LCN-4 or K4LCN-8 processors.
